Abstract : A systematic examination is made of many of the highest valency halides, oxyhalides, and oxides of the elements in their interactions with aromatic hydrocarbons and fluorocarbons. Important to this study is the disappearance of colr in the frozen mixtures of many weakly interacting materials that occurs when a binary system exhibiting an intermolecular charge-transfer transition produces a simple eutectic phase-diagram. The following generalizations were tested: The covalent, highest-valency halides, oxyhalides, and oxides of the elements include high electron-affinity molecules that demonstrate charge-transfer spectra with the strictly pi-donors, such as aromatic hydrocarbons and fluorocarbons; Such pi-donors produce stable complexes only in close 'plane-to-plane' type, the associations are very weak or just contact. Two major reasons for the weakness of the interactions are suggested. (Author)
